    alright i had the check engine light come on and one of the codes i pulled was p0031 HO2S Heater Control Circuit Low (Bank 1 Sensor 1). my question is where is this located and where can i buy one online? i looked on rockauto.com and cant tell if i need a downstream or upstream? too many choices. its under the emissions section then o2 sensors and there are two denso oem type sensors to choose from and a bunch of other ones. anythoughts

    One of the codes? I think maybe it would not be a bad idea to replace all the sensors. How many miles on them? usually when one goes, the others are not far behind. Pay now ,....or pay later. Good luck with it.

    you should also purchase a can of this to spray on the nuts before attempting to change out the sensors.

    no problem. it sucks having the CEL on, especially when the outcome is brutal gas mileage.
